Leave only bluetooth active

I have a rooted HTC Rezound. Is there an app that will allow me to turn off all wireless services (including phone) except bluetooth? I want to be able to use my bluetooth keyboard in areas of spotty Verizon coverage without draining the battery as the phone polls for signal.

The easiest way I can think of is using Tasker. You could either create a 1x1 widget button that could disable everything except Bluetooth, or make everything be disabled automatically when your keyboard was connected if that is what you want.
